A still better effect will be produced by a Magnetic Battery, consisting of a number of simple magnets, united with their poles in the same direction; and which will be nearly as strong as the sum of the forces of the individual magnets; a portion of the force being lost by the cross attractions of the N poles for the S poles etc. Saturation.
We report, for the first time, facilitation between an exotic and a native bark beetle seems to involve overlap in the use of host attractants and pheromones, which is cross-attraction.
arrive on loblolly pines attacked by D. frontalis within 1 3 days of attacks by D. frontalis, facilitated by considerable chemical cross-attraction among these species [29] [31].
Cross-attraction of bark beetle species is fairly common in North America and Europe, particularly with respect to compounds produced by host trees, such as ethanol and monoterpenes, and pheromones, such as ipsenol and ipsdienol [22] [23].
Results from our bioassays provide evidence for cross-attraction among orchid taxa towards patrolling males of C. cunicularius and A. nigroaenea.
The cross-attraction of each parent orchid species to each pollinator was allowed by the emission of (at least partly) overlapping patterns of biologically-active compounds for each pollinator species [Additional file 2: Supplemental Table S1].
If our chimp-homo hybrid ancestors did indeed also hybridise with ancestral gorillas, could this ancient cross-species attraction help to explain the attraction some women felt for Guy the gorilla and their bizarre offers of help in a hybridisation programme?
The model demonstrates a picture of the initial Hb profile crossing the attraction basin boundaries similar to the first family case in Figure 5C, but with a smaller variance (Additional file 16: Figure S11).
One map on the site helps search for parking garages in New York, not just by neighborhood, but also by address, cross streets or attraction (museums, theaters, sports exhibits).
Adding a green cross vane deterred attraction of non-pest species such as bees, but did not compromise catches of the target pests.
The cliché about spying is that it is like a fairground hall of mirrors, but reading Double Cross, such an attraction does not really seem worth spending good money to visit.
